Abstract (en)
[origin: CA2944754A1] A distributed amplification device (2) with p inputs, p outputs, p amplification paths comprises a redundant reservoir (4) of n amplifiers (56, 58, 60, 62, 64, 66, 68, 70, 72, 74) including n-p back-up amplifiers (56, 74), an input redundancy ring (48) and an output redundancy ring (50) formed by rotary switches, the input and output redundancy rings (48, 50) sharing the same technology. The internal amplification pathways (76, 94) associated with the n-p back-up amplifiers frame in an interlaced manner the internal amplification pathways associated with the p nominal amplifiers (58, 60, 62, 64, 66, 68, 70, 72) and the amplification paths of the routing configurations each pass through at least five rotary switches. The input and output redundancy rings (48, 50) are topologically and geometrically configured and the family of the routing configurations is chosen such that the electrical lengths of all the paths of one and the same routing configuration (172) of the family are equal.
Abstract (fr)
Un dispositif d'amplification répartie (2) à p entrées, p sorties, p chemins d'amplification comprend un réservoir redondé (4) de n amplificateurs (56, 58, 60, 62, 64, 66, 68, 70, 72, 74) dont n-p amplificateurs de secours (56, 74), un anneau de redondance d'entrée (48) et un anneau de redondance de sortie (50) formés de commutateurs tournants, les anneaux de redondance d'entrée et de sortie (48, 50) partageant la même technologie. Les voies internes d'amplification (76, 94) associées aux n-p amplificateurs de secours enserrent de manière entrelacée les voies internes d'amplification associées aux p amplificateurs nominaux (58, 60, 62, 64, 66, 68, 70, 72) et les chemins d'amplification des configurations de routage traversent chacun au moins cinq commutateurs tournants. Les anneaux de redondance d'entrée et de sortie (48, 50) sont topo-logiquement et géométriquement configurés et la famille des configurations de routage est choisie de sorte que les longueurs électriques de tous les chemins d'une même configuration de routage (172) de la famille sont égales.
